Abstract
The development of new network communication protocols has to include a process of concept evaluation in order to prove its soundness. Simulation-based techniques provide assessment of communication quality in complex and realistic working conditions. This paper introduces a novel and unique simulation technique, by merging QualNet simulator and SDL protocol developer. Many complex modifications of the QualNet nodes can be efficiently implemented, which is very difficult by a straightforward re-coding of QualNet components. The proposed methodology was utilized in the development of a wireless heterogeneous IEEE 802.21-based network. The paper provides a detailed insight of the model's three basic parts: QualNet environment, SDL resource manager and the novel SDL2QualNet interface. We present useful information for 802.21 simulation implementation, data acquisition from QualNet and calculation of dynamic network parameters, information and buffer management, methods for improvement of simulation efficiency, and many other modeling hints which enable a comprehensive simulation platform.
